Reading a Goa GSTIN
30AAAAA0000A1Z5
The first two digits (30) are the state code, the next ten the business's PAN, the 13th the entity number, and the 15th a checksum. Verify any number instantly with the GSTIN validator.
CGST + SGST or IGST?
Selling within Goa — seller and place of supply both under code 30 — splits the GST equally into CGST and SGST: an 18% supply becomes 9% + 9%. Selling from Goa to any other code (or buying in from one) makes it an interstate supply with a single IGST line at the full rate. Your customer's GSTIN prefix is the quickest way to know which applies.
